SPARK-ARRESTER.

SPECIFICATION forming part of LettersPatent N 0. 770,638, dated September 20, 1904.

Application filed March 31,1904:-

, as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in spark arresters for locomotive and other smoke stacks.

The object of the invention is to provide a spark-arrester which when inserted into a stack will effectually prevent any sparks being discharged from the stack, but will allow the smoke to readily pass from the same, means V being provided for conducting the sparks .to a suitable receptacle.

A further object is to provide means for regulating the draft through the stack. 7

VVith' these and other objects in View the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a vertical sectional view showing the application of the device to the smoke-stack of a 10- Fig. 2 is a detail side elevation of the. device removed from the stack. Fig. 3 is a fragmentary detail View showing the manner of holding the arrester in place.

Referring more particularly to the drawings, 1 denotes a smoke-stack, which is here shown as a locomotive-stack having an enlarged flaringupper end 2. In said upper end of the stack is arranged the smoke-arrester 3, which consists of a conical-shaped frame formed by an annular band or collar 4:, to which is secured upwardly-projecting converging bars 5, connected at their upper ends to the inner end of a pipe-elbow 6. Arranged on and supported by the conical-shaped frame is a cone 7 of wire-netting. Within said wirenetting cone and projecting from the lower end of the same is arranged an inverted defleeting-cone 8, formed, preferablygof sheet said hangers to said bars.

Serial No. 200,923. (No model.)

hangers or braces 9, which are secured at their lower ends to the upper end of the cone. The upper ends of the hangers or braces 9 are provided with vertically-disposed slots 10, through which and through the bars 5 of the wire-cone frame pass bolts'12, on which are screwed clamping-nuts 13, which firmly clamp Upon releasing said nuts the slots in. the hangers 9 and the spring construction of the same will permit the cone 8 and the hangers to be moved up or down, thereby regulating the draft of said stack, as will be understood.

To the free end of the elbow 6 is connected a downwardly-inclined section of pipe 14, to the opposite end of which is connected by an elbow 15 a Vertically-disposed pipe 16, which is supported by braces 17, connec .d to the same and to the stack, as shown. fhe lower end of the pipe 16 enters the upp r end of a pipe 18, closed at its lower end to form a receptacle to receive the sparks drawn through the cone 7 and pipe 16, the saidlower end of the pipe 16 being of smaller diameter than the pipe 18 to provide an intervening space 18", forming an outlet for the escape of the smoke from the receptacle. The section of pipe 18 is supported by means 01 a finger 19, which hooks over a horizontally disposed yokeshaped bar 20, secured to and projecting rearwardly from the stack, and is removable therefrom to enable the sparks and cinders received by the same to be emptied out.

While a receptacle formed by the pipe 18 is shown and described as provided to receive the sparks, it is obvious that the pipe 16 may be continued and connected with the fire-box, thereby discharging the sparks and cinders passing through the same into said fire-box.

In order that the arrester may be held in place in the stack, a curved hook 21 is pivotally connected to the upper end of the stack to hook over the section of pipe 14 and engage a similarly-connected curved eyebolt 220m the opposite side of the pipe, thus removably securing the arrester in place.

From the foregoing description, taken in connection with the accompanying drawings,

the construction and operation of the invention will be readily understood Without requiringa more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing-anyof the advantages of this invention;

Having thus described my invention, what I claim as new, and desire to secure .by Letters Patent, is

1. A spark-arrester adapted to be placed in a stack so as to arrest cinders and comprising a perforate cone, a deflector-disposed at the base of the cone to direct the products, &c., upwardly into-.contact with "said cone, andan escapepipe xconjimunicating with the top of the-cone, substantially as described.

2. A spark-.arrestenadapted to be placed in a stack soastoarrest cindelksand comprising a frame, :a wire-netting.conessupported by said :frame, an inverted coneadjustably @supported in-the base of said ,wirelcone, and an exit- -pipeconneeted :to the upper end! of the cone -.t0-conduet sparks, cinders ;and :lt le like to :a suitable ireeeptacle', substantiallyras described.

-.3. .A-smoke-armstenadapted;to.;be placedin a stack soestoanrestcinders andvcomprisiing a conical-shaped frame consistingrof a bandor collar, and upwardly-,projectingconverging bars -,a .wire netting .cone supported by said BEST AVAlLABLE CCP" frame, an inverted cone adjustably mounted in said frame within the mouth or lower larger end of the wire cone,-slotted hangers secured at their lower ends to said invert-ed cone, bolts connecting the slotted upper ends of said hangers with the bars of said frame whereby said inverted cone may be adjusted, clam ping-nu ts adapted to be screwed onto said bolts, whereby said hangers and cone will be supported in theiradjusted positions, and an exit-pipe connected to the upper smaller end of the wire cone for conducting the sparks caught by said Wire cone to a suitable receptacle.

4. Aspark-arrester adapted to be placed in a stack so as to arrest cinders and comprising a conical-shaped frame, a wire-netting cone supported bysaidframe, an inverted cone, adjustablymounted in said frame and within the mouth or lower larger end of the wire cone, an exit-pipe connected with the upper smaller end of said wirecone to receive the sparks caught by said cone, and a-receptacle for the sparks communicating with Said exit pipe, substantially as described.

In testimony whereof I have hereunto set my handiin presence of two subscribingw'itmesses.
